Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that automatically pulls out various adhesive tapes by a predetermined length, cuts them, and affixes them to a desired position on an object. . Conventionally, we have not seen any equipment that automatically applies this type of adhesive tape, but when we actually researched it, we found that because the tape is adhesive, it is extremely difficult to handle mechanically. I understand that although there was a desire for this type of device, it never materialized.
The present invention solves this difficulty. Simply place the object in a predetermined position on the device, press the switch, and the tape of a predetermined length is automatically pulled out, cut, and glued to the target object in a predetermined position. It is convenient because it has a piece of tape attached to it. Conventionally, when applying adhesive tape to an object, one would pick up the end of the tape with one's fingertips, pull it out, cut it with a serrated cutter to create a short piece of tape, and then paste this onto the object. When the instant tape turns or twists, or when you have to hold the object with one hand and apply the tape with the other, it becomes extremely difficult to apply the tape, and you experience that the work is inefficient. In comparison, it can be seen how convenient the device of the present invention is.

An example of implementing the present invention will be described with reference to the drawings. In Figures 1 to 3, 1 is the front frame plate, 2 is a connecting bolt that connects this to the back frame 3, and 4 is the base 5 and 1.

Since the ordinary tape 10 is wound around a ring-shaped paper tube 9, it is configured to be attached to the holder 6 as is. 7 is a stopper provided to prevent the tape from coming off. Guide rolls 11 and 12 are used when drawing out the tape, and as shown in the figure, they come into contact with the back surface that is not wetted with adhesive liquid, and the tape is guided downward into the apparatus. 13 is a tape end stopper which is shaped when viewed from above, and 16 is a saw blade shaped cutter attached to the end face thereof. Reference numeral 15 denotes a tape pulling mechanism, and its structure is such that a tape gripping rod 20 that is vertically slidable is housed in a sheath body 17, and a tape gripping roll 23 is engaged with the tape gripping roll 23 at the lower end thereof, and a cam 31 is engaged with the upper end thereof. This is provided with a roll 25 that does this. Also,
The sheath body 17 itself is pivotally attached to the inside of the front frame plate 1 by pins 18. Reference numeral 21 denotes a tape gripping piece that projects slightly upward from the lower end of the sheath body 17, and grips the tape in cooperation with the tape gripping roll 23 (FIG. 5). Reference numeral 22 denotes a notched groove provided in the lower sheath of the tape gripping piece, which serves as a path for vertical movement of the tape gripping roll 23 as the tape gripping rod 20 moves up and down. The end of the tape is fixed on the cutter 16, the tape gripping roll 23 is located below the horizontal portion 10' (FIG. 2) of the tape, and the tape gripping piece 21 is located above it. 26 is a pin projecting slightly above the lower end of the sheath body, 27 is a pin projecting from the lower end of the tape gripping rod 20, and a compression spring 28 is stretched between both pins. In this way, the tape gripping rod 20 is always given a force to be pulled downward within the sheath.

Next, regarding the cam mechanism, in FIGS. 4 and 5, 36 is a drive gear driven by the motor M, and 31 is a cam integrally connected to the gear 36. 32 is a cam groove, and 33 is a rim provided on the outer periphery. A roll 25 provided at the upper end of the tape gripping rod 20 is engaged with the groove 32, and a notched inclined groove 24 is formed in the rim 33 of the cam, and a spring plate 35 is attached to the left rim end of the inclined groove. Pivotally supported 34. The spring plate reaches the bottom of the cam groove 32 obliquely as shown in the figure. Another inclined cam groove 44 is formed at a position substantially opposite to the inclined groove 24.

Next, as for the tape drawer mechanism, the 4th to 7th
In the figure, 38 is a driven gear that meshes with the driving gear 36, 39 is a pin protruding from the side thereof, and 40 is a sheath body 1.
It is a pivot pin protruding from the center of 7, and both pins 3
9 and 40 are connected by a connecting rod 41. Reference numeral 42 denotes a long groove provided at the upper end of the connecting rod, and as the gear 38 rotates, the pin 39 moves within the long groove and the lower end 43 of the groove.
When this is reached, the connecting rod 41 is operated to push it, and the tape gripping mechanism 15 is further operated to be pushed in the direction of the arrow C via the pivot pin 40.

Finally, regarding the adhesive tape cutting and pasting mechanism, in FIGS. 2, 3, and 8 to 10, 45 is a rack that meshes with the drive gear 36;
47 is a rack guide, and 47 is a connecting rod fixed to the lower end of the rack.As shown in FIG. The tape passes through the groove 14 and reaches the front surface of the front plate 1, and 48 is a tape attachment body attached via a connecting rod 49 attached perpendicularly to this connecting rod 47, as illustrated in the figure. , a tape sticking plate 50 is attached via two mounting rods 51, 51', and a T-shaped tape holding plate 5 is attached to the left end surface.
2. The lower end 53 of the tape holding plate extends slightly downward from the lower surface 50' of the tape sticking plate 50, and the convex portion 57 at the center thereof fits into the vertical shaft 54, and is connected to the vertical shaft. It is pressed downward by an engaged spring 55. As can be seen in the figure, there is a slight gap between the tape holding plate 52 and the left end surface of the tape sticking plate 50, and when the tape sticking plate 50 is lowered, the saw blade-shaped cutter 16 is inserted into this gap. invade. By lowering the tape application plate 50, the tape is first pressed by the lower end 53 of the tape presser plate, and then the tape is cut by the saw blade cutter and the edge 59 of the tape application plate 50.

The present invention has the above-mentioned structure, and to explain its operation, first, as a preparation, the adhesive tape is pulled out and the end portion thereof is fixed on the saw blade-shaped cutter 16 as shown in FIG. put. Place the adhesion place B of the article A to which the adhesive tape is to be applied at the predetermined position on the machine as shown in the figure. That is, the pasting part B is located approximately at the center of the apparatus, below the tape 10' which will be pulled out soon, but its position is easily recognized. When the motor M is driven in this manner, the drive gear 36 rotates at an appropriate speed in the direction of arrow A in FIG. Since the cam 31 is integrally connected to the gear 36, the cam also rotates and the cam groove 3
The roll 25 that engages within the spring plate 3 (FIG. 4)
5 and is pushed up to the surface 33' of the cam. Therefore, the tape gripping rod 20 also has a spring 28.
The tape gripping roll 23 at the lower end of the rod also rises (the sixth
(Fig.), the roll pushes up the end of the tape, and eventually the end of the tape is held between the tape gripping pieces 21.
During this operation, the roll 23 comes into contact with the adhesive surface of the tape, so that the tape is reliably moved.

On the other hand, as the gear 38 rotates, the pin 39 on the gear rotates and initially moves within the long groove 42 provided at the top of the connecting rod 41;
3, the pin pushes the connecting rod 41 and connects the tape gripping mechanism 1 via the pivot pin 40 on the sheath body 17.
Push 5 to the right to get the state shown in Figure 7. At this time, since the end of the tape is gripped by the tape gripping mechanism, the tape is pulled out and stretched like 10'.

During this time, the rack 45 that engages with the gear 36 continues to descend, lowering the tape application body 48, and as shown in FIG. Press down on the tape. The tape holding plate is a tape end stopper 1.
However, the tape-applied body 48 continues to descend further against the compression spring 55, and is pushed by the left edge 59 of the tape holding plate 52 to pass over the saw-blade cutter 16. Cutting the stretched tape 10' at the cutter position,
The cut adhesive tape short piece 10' is attached to B of article A.
It is pasted by pressing it onto the surface (Fig. 8). Automatic pasting is now complete. Since the pressing force during pasting is applied elastically by the action of the spring 55, there is no damage to the article.

When pasting of the tape is completed, a command to reverse the rotation and return to the old position is issued to the motor M (not shown), and the device returns to the state shown in FIG. 2 again. Therefore, continuous work is easy.

Note that by appropriately selecting the length of the connecting rod 41 and the position of the pivot pin 40, the amount of tape drawn out 1
0' can be adjusted to the desired length, and
Since the tape gripping roll 23 comes into contact with the adhesive liquid of the adhesive tape, the roll surface tends to become dirty, but in order to prevent this, it is preferable that the roll surface be subjected to special treatment such as Teflon treatment.

Next, a modification of the device of the present invention will be described. The one shown in FIG. 9 is of horizontal type, and the portion to be attached to the adhesive tape extends over both the upper and lower surfaces of the protruding edge 60. Even in such a case, the mechanism of the device remains the same, and the shape of the tape attachment plate can be simply changed. In the figure, 60, 60 are the edges of the lid and body of the box, which protrude from the main body. 61,
Reference numeral 61 denotes a pair of levers that are pivotally connected to the tape application body 48 and are bent at the center and opened outward from each other, and the tape application roll 62,
62 is attached, and springs 63, 63
It is constructed so that it can be opened and closed.

Now, even in the case of horizontal type, due to the rotation of motor M,
Each mechanism operates in the same manner as in the case of the vertical type, and when the tape pasting body 48 advances to the left in the figure, the tape pasting roll 62 cuts the tape on the serrated cutter 16, and the short piece 10' is cut. obtain. By continuing to push this to the left, the tape can be applied to both the upper and lower surfaces of the ridge 60.

As described above, the device of the present invention automatically pulls out the adhesive tape to the required length, cuts it, and attaches it to the object.The device automatically places the adhesive tape in the desired location while manipulating the object with both hands. It is an extremely convenient and efficient device that can be applied, and there is no problem of pasting failure due to twisting of the tape.
